C A R S EAT SPECIFICATION forming part of Letters Patent- No. 425,424,dated April 15, 1890.

Application liled April 20, 1889. Serial No. 308,014.. (No model.)

T0 @ZZ whom it' may concern.:

Be it known that I, FRED Il. HENRY, of Vv-Takeield, in the county ofMiddlesex, in the State of Massachusetts, have in-vented a new anduseful Improvement in Car-Seats, of which the following is aspecification.

This improvement relates to that class of car-seats in which thereversible seat-back is locked when it is dropped into position bygravity, and when it is in such position does not drop behind the seat,but remains with its lower edge above or substantially on a level withthe surface of said seat.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure l is an end elevation of a carseat embodyingmy invent-ion, portions being broken out the better to illustrate thesame, and the two positions of the seat-back being represented in fulland broken lines. Fig. 2 is an enlarged sectional detail vshowing theoperation of the device. Fig. 3 is a section on line .fr :12, Fig. 2.

A represents the frame, of which A is the arm, and B an `upright orpost, by means of which the seat-back is supported and over which itswings.

C is the cushion of the seat, and D the back.

E is a plate secured to the frame D of the seat back, and provided withan integral disk-shaped tongue E', said tongue having on its peripherytwo notches e e. This plate is chambered out on the line of a circle oneach side at E.

H is the back arm or striker arm, one end of which is pivotally securedat b to the post or upright B, the other end being made thicker at I-land bifurcated or split at h, and shaped, as shown, so that the twoouter ends ot the bifurcated portion are circular or diskshaped at Il,and being secured by means of the pivot I to the disk portion E of heplate E, tit into the circular recesses or chambers E". Pivotallysecured Within the bifurcated portion of the arm I'I at Yo is a pawl K,provided with two teeth K of substantially the shape shown.

lVhen the seat-back is in the position shown in full lines in Fig. l,the paivl, having dropped by gravity, is in the position shown in Fig.

2-tha-t is, with its upper tooth K in engageinent with. the upper notche on the periphery of the disk-shaped tongue E. (See Fig. 2.) When theseat-back is reversed, the pawl K drops by gravity, releasing the notchabove mentioned as being in engagement, and engaging by means of itsother tooth K the other notch e and allowing the seat-back to assume theposition shown by broken lines in Fig. l. It will be noticed that theangle is the saine in both cases and the seat-back is prevented fromdropping behind the seat directly by the paWl K and notched disk E.

The means ot' the pivotal support of the inner end of the back arm orstriker-arm H is not described in detail, as it is not new in thisinvention. It is found in practice that in car-seats of this style-thatis, in which a reversible seat-back is locked by a gravi typaWl when itis dropped into positionthe pawl not infrequently sticks, from one causeor another, and does not drop and lock the seat. In this invention thepawl by being in the position shown is in plain sight and readilyaccessible, so that if it fails to drop by gravity from any cause it canbe readily pushed into position by the finger. This of course cannot bedone Where the pawl is boxed iu ont of sight and out of reach. Therelative position of the pawl is such that it can be made very strong,has a long leverage, and Jthe bearing is directly on its end and on aline with its length.

Having thus fully described my invention, what I clai 1n, and desire tosecure by Letters Patent, is-

In a car-seat, the combination of the following parts, viz: the plate E,secured to the frame of the seat-back, the tongue E', integral with saidplate, notched at e e, and with the portion of its edge or peripherywhich extends from the seat-back of even thickness with its central orbody portion, the striker-arm H, pivotally secured to the post B,extending up from the seat-frame, said striker-arm being bifurcated orcored out at 7L, and the double-acting gravity lever or pawl K, providedwith the teeth K', pivotcd in said bifurcation and swinging in and outof the same in plain sight, and accessible on both sides ot' saidstriker-arm, the ends T of the bifurcated portion of said striker-armbeing pivotally secured to the portion E of said plate, all constructedand arranged substantially as set forth.
